Vista 64bit + FSX benchmark on my system

I think I have a pretty high-end system, at least for a home rig.
I have a i7 920 CPU, P6T deluxe mainboard, 4Gb 1600Mhz RAM and a Nvidia X295. It is not a cheap system. Probably not the best value-for-money around, but definitely high end.

How does FSX perform on such a rig? Badly (not much of a surprise). There are tons of benchmarks on the web, so I am not going too much into detail here. The main fact is that FSX is not designed to make full use the (awesome) computing power of the latest CPU and GPUs.

But, with such a machine, I thought it may be interesting to give Vista 64 bit a try. I will not go into the details of the test, but on my system, FSX on Vista 64 in DX10 preview mode outperforms clearly XP.
Basically, I first defragmented all the hard disks. Then switched off the computer, fired up XP, FRAPS and FSX. And measured how many fps I get, using the Sitka approach mission as a reference.

Numbers were as follows:
Windows XP (32 bit, DirectX 9.0): 10 fps
Windows Vista 64 (DX 9.0): 11 fps
Windows Vista 64 (DX10 previews): 23 fps

FSX was set with ALL the sliders maxed and all the options checked (bloom, scenery shadows, antialiasing, anisotropic filtering everything to the max). Screen resolution was 1366x768 (I know it is low but I use FSX on a 42" plasma TV). No other tricks/special tweaks and clean FSX installations.

As FSX is a 32 bit application I tend to believe that the performance increase was more due to the DX10 than the rest. Whatever the reason, for my system, the verdict is: Vista 64 bit + Direct X 10 largely outperforms Win XP 32 bit for Flight Simulator X.

May I know what level of anti-aliasing you used? Was it 16Q? Thanks.

Wow, that's pretty good performance using any of those OSs.

As for the AA I just turned it on in FSX. Nvidia panel was set to "Application controlled" so it was probably at 2X

The overall performance is not bad...but still disappointing if you see the performance in other games...
